Owenweeksia salterni sp. nov., a Marine Bacterium Isolated from Seawater in the Saltern

Abstract

A novel Gram-negative rod-shaped aerobic and motile strain, designated MEBiC 09403T, was isolated from seawater in the solar saltern of the Jeolla province, South Korea. Strain MEBiC 09403T produces orange-coloured colonies on Marine Agar and posses a single polar flagellum. On the basis of 16S rRNA gene sequence analysis, the closest relative was Owenweeksia hongkongensis DSM17368T with 93.3% similarity and followed by Phaeocystidibacter luteus PG2S01T with 89.9% similarity. Growth was observed at 12.4&#8211 33.5 ℃ (optimum, 21 ℃). When assayed with the API Zym systems acid phosphatase, alkaline phosphatases, leucine arylamidase and valine arylamidase activities were present. Based on phenotypic properties and phylogenetic data, strain MEBiC09403T should be classified within the genus Owenweeksia and suggest O. salterni sp. nov. with strain MEBiC09403T is proposed.nd posses a single polar flagellum.
